When I taught the class Four Season Food Production at J. Sargeant Reynolds Community College, the first project of the semester was a 100 Mile Food Plan. Working in groups, the students were to imagine their food supply was going to be disrupted and their only food, beginning January 1, was going to be from local sources. The project was due in mid-September, so they were to feel fortunate that they had this heads-up months in advance. In real life disruptions occur with increasing frequency with no advance warning. They would have to source their food within a 100 mile radius of where they lived.

The students would need to find sources for winter food and be able to store it or preserve it now. Or, they would need to know a farm where they could buy it as needed, since the grocery stores would be closed. They could grow it themselves, of course, but that would take awhile and winter was coming on. This was a year-long plan, so growing it themselves would be planned in. If the animal products in their plan depended on feed shipped in and not grown locally, that would be a consideration.

My intent in assigning this project was to acquaint them with the local food system. I wanted to get them out to the farmers markets to talk with the farmers and find out what was available. I also wanted them to think about exactly what it was they ate and how much they needed for a year. They received extra credit if they brought in a highway map of Virginia with their location pinpointed and circles at 25, 50, 75, and 100 miles away. It had to be a highway map so that it showed all the localities. When they first thought of this 100 mile limit, many students thought it would severely limit their choices until they actually put the circles on a map. Even if you are not familiar with Virginia, you can see from my map that there are mountains on the left and the ocean on the right—all within 100 miles from my house as the crow flies. The area goes north into Maryland and dips into North Carolina to the south. Make a map of your own and see what you would have to choose from.

This project sure was an ice-breaker. One thing that always happened in my classes was that people talked to each other. Each group had to assess the strengths of each of its members. Someone may have land available for future growing and others may have money, tools, skills, storage facilities, or muscle to contribute to each “community”. They would need to show on a chart what foods they found and where, how much they would need of each food for the year for their group, and how it would be stored or preserved. I also wanted their comments on what strengths and weaknesses they found in our present local food system. This generated plenty of discussion about what would happen if everyone had to suddenly depend on these local sources and what, if any, changes in their lifestyle and diet this project encouraged. I always enjoyed the interaction among everyone. I remember one group that had both a long-time vegan and a young woman whose family ate mostly meat. When you are planning for a community, everyone must be considered.

When I first started teaching at the college in 1999, farmers markets were few and far between. It amazes me how many there are in 2013, with the number growing each year. I was one of the founding farmers of the Ashland Farmers Market. I stopped selling vegetables after the 2001 season to concentrate on teaching in order to put more knowledgeable consumers and producers at the markets. The produce, meat, eggs, and honey sold at the Ashland market must have been grown within a 30 mile radius of the town. If shown as a circle on my map, it would be just outside the inner circle. Most markets don’t have such a limit. Besides farmers markets, there are many other options for people to connect with local growers. You can find sources for food grown in your area by checking www.localharvest.org.

The two items my students had the hardest time finding were grains and cooking oil. There was much discussion about the possibility of making oil from the black walnuts that are prevalent in the area. That was before the Piteba, a home-scale oil press, was available. Even with that press, I’m sure the novelty of making oil from walnuts would wear off quickly. There was also much discussion about a source for salt. To really learn, you need to begin with questions and my students generated lots of questions while doing this project. You are probably familiar with Barbara Kingsolver’s book Animal, Vegetable, Miracle, a story of one family eating locally for a year. Once that book came out in 2007, many people began to think seriously about where their food comes from. About the same time, the book Plenty by Canadians Alisa Smith and J.B. Mackinnon was published. This couple had fewer resources than Kingsolver’s family did. They ate a lot of potatoes and tried their hand at sauerkraut which smelled up their small apartment. I encourage you to read both books.

It can be quite a shock to your system to change your food supply suddenly. It is much better to ease into it and make changes gradually if you want them to last. The change needs to start in your mind, and that’s why I had my students do this project. I didn’t expect them to come up with all the answers to a plan that could be implemented right away. That would take much more planning. I did expect them to begin to question their diets and food sources. It certainly got them to focus the rest of the semester on actually growing their own food.

The next project was on cover crops and then there was one about designing a season extension structure to cover a 100 ft² bed. Although it was not required to build the structure they designed, many students did and managed to get it planted that fall. With the first project, all agreed that if we actually had to depend solely on local supplies, there would not be enough food for everyone. With that in mind, they went ahead and built their structure. For the last project, each student was assigned a vegetable and had to write a newsletter about it as if they were a farm and this was their featured product for sale. I left the college in 2010 to be able to address a larger community. The classes continue with my daughter Betsy Trice as the instructor. Betsy has put her own spin on the classes, but she still assigns the 100 Mile Food Plan. If all the grocery stores were to close on January 1, where would your food come from?

This is the fourth year, of the past five, that I’ve eaten only what I’ve grown on the Fridays in Lent. I call these days Homegrown Fridays. I find that it deepens my understanding of what it takes to feed ourselves when I limit myself to only what I’ve grown. By this time of year stored food supplies are diminished and the garden is not quite awake. Our garden and food preservation program has evolved to depend on staple crops that can be stored, rather than canned or frozen. Although I did do a little canning this year, most of the things that couldn’t be stored properly to keep were dried in our solar food dryers.

In the photo you will see one of our Homegrown Friday dinners. It consisted of cowpeas, sweet potatoes, peanuts, and collards fresh from the garden. I often try new things on these days and that day I boiled peanuts. We (my husband and I) decided that eating them raw or roasted was our preference. I depended a lot on peanuts at lunchtime this year. Maybe it was because I seemed to be extra busy on these days. I’d grab some peanuts while sweet potatoes were cooking for lunch. My peanut harvest had picked up in 2012 when I planted some after Austrian winter peas in the rotation. The previous year I had peanuts in a bed following onions and garlic. At harvest time there was a definite difference in the yield in the onion half of the bed compared to the garlic half. Winter peas were the winter cover crop preceding the onion sets that had been planted in the spring. I was pretty sure that the increased peanut yield was due to the winter pea cover crop and not the onions. In 2012 I planted one bed of peanuts after winter peas and one in a bed that had had garlic, onions, and kale. The onions were multipliers and had been there with the garlic and kale since the previous fall. The yield following the Austrian winter peas was three times the one following the alliums and kale.

roasted carrots and beets with black walnut oil

I had a great carrot harvest this winter. You can read about it in my post on Winter Carrots. I also had beets in the garden through the winter. The black walnuts yielded in 2012 so I shelled some and made some oil to put on the carrots and beets when I roasted them. Shelling the walnuts and pressing oil took a long time. I wouldn’t want to depend on that for my cooking oil. Frying locally grown bacon and saving the fat for cooking is a lot easier, but that wasn’t an option for these Fridays, since I hadn’t raised the pig. The roasted carrots and beets were delicious.

Soup made from dried ingredients is always on the menu during this time. One soup I made had no dried ingredients. It was made from carrots, butternut squash, and garlic. I cut them up and roasted them—no oil that day. Then I added water and simmered the cut up, roasted vegetables for about 20 minutes. It all went in the blender and resulted in what you see in this third picture. It was good, but a little bit of dairy added—sour cream, yogurt, or milk—would have been nice. Onions would have been a good addition, but I was down to my dried onions and they were in short supply.

butternut squash, carrot, and garlic soup

Dried onions went into bean burgers using the same recipe as I did in 2012. Our staples for these meals from stored crops were sweet potatoes, peanuts, cowpeas, garlic, sorghum (for flour) and corn (for cornmeal). Fresh from the garden came collards, kale, carrots, and beets. I ground Bloody Butcher corn to make cornmeal mush for breakfast. We have chickens, so we have eggs. I use an egg or two occasionally on Homegrown Fridays, but not much because I don’t grow all the feed for the chickens. Since some of their nutrition comes from our property, an occasional egg is included. Dried tomatoes were important for sauce and other dried vegetables and herbs provided variety in our meals. I’ve already written about our new tea ingredient—Red Thai Roselle Hibiscus. With such a great honey harvest last year we could sweeten our cornmeal mush. Unfortunately, our two beehives didn’t make it through the winter, so I’ll be looking for new bees this year. We had mead made from our honey and grapes, and popcorn cooked without oil.

Observing Homegrown Fridays at this time of year makes me more determined to work out my vole problem with the potatoes to make sure I have enough to last through the winter. I’m also acutely aware that I need to up my wheat harvest. I had an interesting conversation with Eli Rogosa of the Heritage Wheat Conservancy in January while I was preparing an article for Mother Earth News that will appear in the June/July 2013 issue. Eli filled me in on heritage wheat and how to grow it. A chart with her recommended varieties for each region of the U.S. will appear in the article. A chart with crops I’ve mentioned here and varieties recommended for each region will also be included in the article. You will be interested in that article if you want to grow staple crops for your meals.

If you have done any of this, even in a small way, I welcome your comments. It is in sharing, both information and food, that we will move forward on this journey.

Once you really begin to plan how to eat a homegrown/local diet you will soon realize that cooking oil is something that is not coming out of your garden or is available from local growers, unless you live in California in olive territory. If animal products are in your diet, that could be a source of fat. I buy bacon locally from a farmer who raises his hogs on pasture and save the drippings for cooking with. Having homegrown oil, however, would be nice, and it just happened that I visited Lehman’s Hardware in 2010 when they first began to carry the Piteba oil press. I bought one and played with it long enough to know that I needed to spend more time learning all the ins and outs to put it to the best use. I was busy building my solar dryers and learning more about them, however, so the oilseed press got put aside. With my 2011 hazelnut harvest and homegrown peanuts, I decided it was time to get it out. Another source for the Piteba is Bountiful Gardens.

The photo shows it all set for action. The press comes with a small bottle with a wick that holds colored lamp oil that you provide. The first photo shows blue lamp oil, but in the closeup photo you can’t see colored oil because it is almost empty. You also need to provide a container to catch your pressed oil as it drips from the slot. Unfortunately, a jelly jar is too wide to fit the space, but I have a small juice glass that is just the right size. There is a small hole in the frame where that glass sets. A funnel could be placed there with a tube that leads to a larger container. You also need to provide the seed hopper, made from a soda bottle. I used a bread pan to catch the oilseed cake after it was pressed.

The small lamp heats up the press cage to help with the oil flow. Light it 10 minutes before you begin pressing. Once things are flowing well, you might be able to extinguish it. Beware! Only have the wick showing the slightest bit or the flame will be too big. If it is too big and you have to adjust the wick, DO NOT grab the wick holder with your fingers while it is hot! Wait until it cools. I’m speaking from experience here.

The first time I used my press I tried some old sunflower seeds that I had here. They were the striped culinary ones, not the black oilseed variety that you should use for oil. Being old they were probably somewhat dry and they immediately stopped it up. The handle stopped turning easily, in fact, it became impossible to turn. When that happens, and it will, you need to take off the large cap and the adjustment bolt. If you’ve had the lamp lit, they will be hot, which is why I keep handy a ¾” wrench to use for the adjustment bolt and a monkey wrench for the cap. Take them off and immediately clean out the cap. You will need a knife to dislodge all the packed seed residue. Wash everything thoroughly, making sure the threads of the cap are clean. If your seeds are too dry, the directions suggest mixing some water with them and leaving them in a plastic bag for two days, then try again.

Immediately after using the Piteba, dismantle and clean it. If you wait, the press cake inside will become hard as stone. If that happens, you can soak everything in water until it softens enough to take apart. Depending on how it is, you may need to leave it soaking overnight, but it will soften enough to clean. Be sure to read all the directions. There is a washer that needs to be coated with edible oil before it goes on the expeller screw when you put it all together to use.

You can go to the health food store and buy any number of seeds to try in the Piteba. There is a performance chart available on the Piteba website that allows you to compare the percent of oil in various seeds. If push came to shove, however, and you needed to provide cooking oil for your household, you would do well to learn as much as you can about using seeds you can grow or find locally. Keep in mind that these seeds aren’t as convenient as the ones from the store. You will need to clean and process them yourself. If you are using sunflower or pumpkin seeds, use oilseed varieties. The seeds of oilseed pumpkins are hulless. The seeds from oilseed varieties of sunflowers are black.

pressing homegrown peanuts

I was anxious to press my homegrown hazelnuts and peanuts. It took forever to shell the hazelnuts, since my nuts are the small native variety. Find out more about growing hazelnuts at Hazelnuts / Filberts In My Garden. The yield for one cup of homegrown hazelnuts, weighing 5 ounces, was 3⅓ tablespoons oil. The yield for one cup of homegrown peanuts, weighing 6 ounces, was 4 tablespoons oil. I used my Master Nut Cracker for the shelling for both the hazelnuts and peanuts. The peanuts went pretty fast with that. I’ll be writing about that nut cracker one of these days.

If you wanted to produce enough oil for one tablespoon a day per person, you would need 1.4 gallons of oil per person per year. In the Master Charts in How To Grow More Vegetables (HTGMV) by John Jeavons, the beginning yield for peanuts is 4 pounds per 100 ft² and the intermediate yield is 10 pounds. The average U.S. yield for peanuts is 7.2 pounds per 100 ft². Let’s consider the conservative 4 pound yield. I need to sow about 8 ounces of peanuts for each 100 ft² planting, so a yield of 4 pounds leaves 3.5 pounds for eating or pressing for oil. At that rate it would take 960 ft² to grow peanuts to produce 1.4 gallons of oil, plus the seed to plant back. Just think, if you had that 7.2 pound U.S. average, it would only take 500 ft². I battle the voles at my place, so my best yield of peanuts has been 3.75 lb. per 100 ft². I’ll have to see what I can do to get my peanut yield up. The HTGMV beginning yield for hazelnuts is 7 pounds per 100 ft² planting. Since hazelnut trees are perennial, you don’t have to save out any seed to plant back, however, some trees may not produce every year.

primitive oilseed press

In 2008 I took this picture of a primitive oilseed press. I don’t know any more about it than what you see in the picture.The seeds are in a small basket. We were at a folklife festival and came upon it at the end of the day. The only person around was a volunteer who said it was for pressing seeds for oil. If you don’t have a Piteba, it might give you some ideas. In The Self-Sufficient Life and How To Live It, John Seymour suggests using a cider press to extract the oil from seeds. You would need to crush the seeds, then wrap them in a cloth. Obviously, you would need to work with a larger quantity of seeds. It might be, now that you have taken a closer look at what’s involved to produce your cooking oil, you might adjust your diet to use less than before. Steaming vegetables might become more desirable than stir-frying. Last week I used my solar oven to bake some snap beans, potatoes, and garlic together with only 1 tablespoon of my newly pressed oil drizzled over the vegetables. It was delicious.
